This paper studies the distributed caching managements for the current flourish of the streaming applications in multihop wireless networks. Many caching managements to date use randomized network coding approach which provides an elegant solution for ubiquitous data accesses in such systems. However the encoding essentially a combination operation makes the coded data difficult to be changed. In particular to accommodate new data the system may have to first decode all the combined data segments remove some unimportant ones and then reencode the data segments again. This procedure is clearly expensive for continuously evolving data storage. As such we introduce a novel Cooperative Coding and Caching C3 scheme which allows decoding-free data removal through a triangle-like codeword organization. Its decoding .
